Scope

IEC 61120-5:1995 addresses safety requirements for specified industrial process measurement and control equipment. The scope covers design principles, protective measures, limits for hazardous energy, testing procedures and marking/Documentation to ensure safe installation and operation. It is intended to apply to equipment used in industrial environments where control and measurement functions could present electrical, mechanical or thermal hazards to personnel or to industrial processes.

Key topics and requirements

• Safety design principles for process measurement and control devices
• Requirements for protection against electrical shock, fire and mechanical hazards
• Functional separation and insulation requirements between circuits
• Tests for verification of protective measures and fault tolerance
• Marking, labelling and safety-related documentation and instructions
• Guidance on suitable installation environments and ambient conditions

Typical use and users

Engineers and designers of industrial measurement, control and automation equipment; product safety and compliance officers; test laboratories; plant safety and maintenance personnel; conformity assessment bodies. The standard is used to guide product development, conformity testing, type approval and safe installation practices in process industries such as chemical, petrochemical, oil & gas, power generation and manufacturing.
